Dollar Tree review: Telemate for debit cards and credit cards and food stamps

The debit, credit cards and food stamp cards are not working with the telemate machine! It shows chip malfunction and some customers get really upset with the cashiers, which is not good, for the customers show their phone app saying it went thru with it did not and they walk out the door with free merchandise. And sometime's register 4 will give cash back when they pushed on. Please help your employees, for they try their best to keep up as good as they can. Please bring the nerds to fix these problems for your losing merchandise, employees and customers.
